I would use a Seafoam Motor Treatment. Put 1/2 in gas tank. Put 1/2 in the plenum (I usually remove the brake booster vacuum line and start the engine and slow pour the 1/2 Seafoam Motor Treatment. The engine will slow bogs down when it's sucking the seafoam motor treatment. Let it sit for 30 minutes or more. The longer it sits the better. I'd suggest doing this outside the house and at night because when you start the engine back, there would be a lot of smoke.

Also, I'd suggest using a catch can.
